Any comments on which champions I should upgrade and add signatures?

Rap027

I’ve never really played her but i hear Guillotine 2099 is a BEAST and getting her as a 5* is HUGE.

Iron man infinity war is solid and a good defender.

As far as 4 stars go: DEFINITELY focus awakened Ægon use all your sig stones on him and rank him up. Ghost is a beast if you can use her well, colossus and captain marvel movie are great too (cmm is worth sig stones too).

Red skull, storm, kingpin, thor jane foster, regular iron man, and vulture all aren’t good at all i would definitely stop wasting resources on them

Thanks only reason why I ranked them up was they were my only 4 stars so i tried to rank them up so i could get other champs. Thanks
